bester MiniMagster 1501 Bedienungsanleitung Seite 8

MiniMagster 1501S is equipped with two input power
cords for two types of power supply. Change of the
power supply can be done by the power supply
switch, which is placed on the rear panel of the
welder.
Before connecting the welder to the power supply
network , make sure if the main switch is "0" (switched
off).
Shielding Gas Connection
To connect shielding gas, you should:
After placing the shielding gas cylinder on the platform,
protect it against to overturn with the chain.
Take off the hub cap of the safety valve of the shielding
gas cylinder.
Install the regulator on the gas cylinder.
Connect the regulator to the MiniMagster with gas hose
using band clip.
Wire Loading
ATTENTION
Before wire loading, turn machine power switch to
the OFF ("0") position before working inside the
wire feed enclosure.
To load wire you should do the following sequence of
operations:
Push the spool onto the spindle so that the wire
feeds off the bottom of the spool, toward the
drive roll.
5 kg spool push onto the shorter part of the spindle
with bigger diameter and 0,5 kg spool push onto the
longer part of the spindle with smaller diameter.
To lock the spool, push the spool spacer onto the
spindle. For 5 kg spool with the spool spacer flange
inward and for 0.5 kg spool with the spool spacer
flange outside.
Slide the spring onto the spool spacer, then press on
the spool lock, turning it clockwise to lock the spool
assembly onto the spindle.
Release the spring loaded thumbscrew and rotate the
idle roll arm away from the wire feed drive roll.
Ensure that the visible, stenciled size on the drive roll
side facing you matches the wire size being used.
Carefully detach the end of the wire from the spool
maintain tension on the wire to prevent the spool from
unwinding.
Thread the wire through the ingoing guide tube.
Thread the wire over the drive roll, and into the gun
liner.
Close the idle roll arm and turn down the thumbscrew
until the idle roller presses down firmly on the wire.
Remove the nozzle and contact tip from the gun.
Turn the machine ON ("I").
Point the gun away so that outgoing wire doesn't cut
the welder and other people standing nearby.
Depress the gun trigger switch and welding wire
should move towards the end of the gun.
ATTENTION
Don't look into the outlet of the gun during cold
inching - going out wire can seriously injure your
eye.
After going out the wire into the gun outlet (about 20
mm), release the gun trigger switch and twist the
contact tip suitable for the wire diameter being used.
Adjust pressure by turning thumbscrew. Pressure too
low – drive roll slips on the wire; pressure too high –
the wire is cut by the drive roll or is locked in the guide
tube. Turning the thumbscrew to the right – pressure
increasing, turning the thumbscrew to the left –
pressure decreasing.

Welding with Positive Polarity (DC+)
As delivered the machine is wired for Positive Polarity.
To wire for Positive polarity, connect the gun cable to
the Positive (+) output terminal and the work cable to
the Negative (-) terminal.
